With respect to the drawings and the numerals of reference thereon, the car body of the invention includes longitudinally extending frame members at the sides of said car body, and transversely extending frame members II at the ends of said car body. Each side frame member l0 consists of a pair of elongated I-beams, denoted !2 and I3, respectively, having the body portions or webs M of said I-beams disposed vertically and parallelly with each other, and having the meeting edges of adjacent upper and lower flanges, denoted. I and I6, respectively, of said I-beams welded together, as shown very clearly at ll. Portions of the meeting edges of the upper flanges l5 and the lower flanges l6 are cut away, and metal l8 to weld said flanges together is placed in said cut-away portions in any well known manner. Also at spaced apart intervals along the lengths of the side frame members Ill, the connected I-beams are desirably reinforced by transverse webs l9 welded to the body portions or webs l4 and to the flanges of said I-beams, as well as by U-bars 20 and filler bars 2| between adjacent body portions or webs l4, the U-bars and filler bars being shown as riveted to the body portions or webs. The transverse webs l9, U-bars 29 and filler bars 2! could be attached to the I- beams in a manner different from that shown. Each end frame member I l consists of an I-beam extending between the side frame members ID, there being an end frame member ll adjacent each end of the car body in spaced relation to the outermost extremities of said side frame members It. The end frame members II are perpendicular to the side frame members Ill. The innermost upper and lower flanges, denoted 22 and 23, respectively, of the side frame members l0 detachably support, as by screw bolts 24, plates 25 at the inner sides of the upper and lower flanges, denoted 26 and 21, respectively, of the opposite end portions of each end frame member H, and said plates 25 are welded to said upper and lower flanges 26 and 21, as at 28. The end frame members or I-beams H are desirably reinforced by transverse webs 29. Said end frame members or I-beams l! are themselves interconnected by spaced apart I-beams, denoted 3G and 3|l, respectively, extending lengthwise of the car body at opposite sides of the longitudinal center thereof. Opposite end portions of the upper and lower flanges of said I-beams 35 and 3| are detachably connected, as by screw bolts 32, to adjacent flanges of the end frame members or I-beams II, the flanges of said I-beams 30 and 3| lying between the flanges of said I-beams ll. Also, the I-beams 39 and 3| include transverse webs 33 at the opposite ends thereof, which webs are bolted, as at 34 in Figs. 1 and 4, to the body portions or webs of the I-beams As shown in Figs. 1, 4, and 5, a plate 35 is interposed between an upper flange of each I-beam II and the flanges upon theadjacent ends of the I-beams 30 and 3|, and said I-beams 3|! and 3| are bolted as at 32 to said plates 35 as well as to the I-beams A pair of reinforcing plates, denoted 36 and 31, respectively, extend transversely of the car body at the opposite sides of the transverse center thereof, said plates 36 and 3'! lying between the bodies or webs of the I-beams 30 and 3| and being welded or otherwise fastened to said I-beams 35 and 3|. As shown more clearly in Figs. 1 and 6, four plates, each denoted 38, are bolted, as at 39, to the upper, outer flanges of the I-beams 30 and 3|, said plates 38 being equally spaced from the vertical axis of the car body and at equal distances apart. Each plate 38 is welded to a channel member 40, as at 4|, and each of the four channel members 40 extends horizontally outwardly toward a corner of the car body. A relatively short I-beam 42 adjacent each corner of the car body extends obliquely to the side and end frame members' I0 and H desirably at a forty-five degree angle to each frame member. The I-beam 42 may include reinforcing webs 43. An end portion of each I-beam 42 is suitably welded to an end frame member or I-beam II, as at 44, and the upper and lower flanges of the opposite end portion of each I-beam 42 are welded to the upper and lower plates 25, as at 45. The body portion or web of each I-beam 42 is welded as at 46 to a vertical plate 47 which is detachably bolted, as at 48, to the body portion or web of the inner I- beam of each side frame member. Obviously, there are four vertical plates 41. In addition, there are four vertical plates 49 bolted as at 50 to the body portion or web of the inner I-beam of each side frame member to which the opposite end portions of each end frame member or I-beam l are welded as at 5|. The outer ends of the channel members 43 are bolted as at 63 to plates 64 welded to the I-beams 42. I

Numeral 65 denotes axles for the car wheels 66, said axles being suitably mounted in the body portions or webs of the I-beams of the side frame members as shown more clearly in Figs. 1, '7, and 8. There are eight car wheels as shown, two at each corner of the car body. The car body may be self, or otherwise, propelled along the tracks The car wheels may desirably be of width to about span the space between the body portions or webs of the I-beams of the side frame members, as will be clear from Figs. 1 and 8, and the lower flanges of said I-beams of the side frame members are cut away, as denoted at 68, to accommodate the car wheels.

A bull gear 52 is associated with the car body in novel and improved manner. Said bull gear may consist of an inner annular portion 53 providing an internal, vertically disposed gear surface or toothed portion 54, an annular upstanding or vertical portion 55 providing an operating rail 56 of the bull gear adapted to constitute a lower rail for supporting a revolvable platform of an excavating or other machine, and an annular horizontal portion or web 51 integrally connecting the lower parts of the portions 53 and 55. The bottom surface of the horizontal portion or web 51 is flat. As disclosed, the bull gear consists of two equal halves each extending 180, and said halves of the bull gear are detachably connected to each other by bolts 58 arranged in reinforcing flanges or webs 59 upon the different halves of said bull gear at the meeting ends of the two halves. The bull gear includes additional reinforcing flanges or webs 59 at spaced intervals about its periphery. In practice, the bull gear can, if desired, be cast as a continuous circumferential member.

Preferably, however, it is when so cast out to provide two diametrical halves detachably connected in the manner as illustrated and described.

As shown in the drawings, the bull gear is placed upon the car body so that the end portions of the detachably connected halves thereof lie directly over the midlengths of the side frame members Ill. .When said bull gear is upon the car body, the circumference of the horizontal portion or web 51 rests upon the upper flanges of the I-beams and 42, as well as upon the upper flanges of the I-beams l2 and 3; that is, upon the side frame members I0. The bull gear is desirably welded, as at 60, to the upper flanges of the I-beams and is welded, as at 6|, to the upper flanges of the I-beams 42. Also, the bull gear is desirably bolted, as at 62, to the side frame members l0 and end frame members I.

It will be evident from the drawings and the above description that the assembly including the car body and the bull gear is detachable into a plurality of separate units of said car body, which separate units are, each of the side frame members In, each of the end frame members II integrally attached to one diametrical half of the bull gear and to a pair of adjacent I-beams'42. each of the channel pieces 40, and the I-beams 30 and 3| integrally connected bythe plates or webs 33, 36, and 31. The plates or webs 33, 36, and 31 may be detachable, and in such case each of the I-beams 30 and 3| is a separate unit of the car body. Obviously, in the disclosure as made, the plates 38 are integral with the channel members 40, the plates 25 are integral with the I-beams l and 42, the plates 64 and 41 are integral with said I-beams 42, and the plates 49 are integral with the I-beams The several units constituting the car body and the bull gear can be transported in knocked down condition and assembled at the location where an excavating machine having the car body and bull gear is to find use, as will be understood. Of course, the several units of the car body and the bull gear can be independently constructed when the machine is being manufactured, to be afterwards assembled together and connected in the manner as set forth. That is to say, while the description as given follows a general sequence to produce the car body with bull gear, this sequence can be altered. For example, the two diametrical halves of the bull gear could be welded to the I-beams II and 42 either before or after said I-beams are welded to each other and while disassembled from the side frame members |0. Also, the structure including the I-beams 30 and 3| can be assembled with the I-beams either before or after the side frame members I0 and end frame members or I-beams I l are assembled. And the channels 40 can be assembled into the structure during any preferred stage of its manufacture. What is meant is, that the units of the car body with bull gear as illustrated and described are not only separate units, but are as well units which can be independently made and, speaking generally, independently assembled together.

A platform (not shown) is adapted to be revolvably supported upon the car body through the instrumentality of a king pin 69, the operative rail 56 of the bull gear 52, an upper rail (not shown) on the platform, and rollers or wheels of a container ring (not shown) between said operative rail and upper rail. The king pin 69 is bolted as at 39 to the upper flanges of the I-beams 30 and 3| and extends vertically upward. Said king pin may additionally be welded to said I-beams 30 and 3|, as well as to the reinforcing plates 36 and 31. The lower portion of the king pin is of rectilinear conformation, and the upper portion thereof is of reduced, cylindrical shape. The king pin is directly above the longitudinal and transverse center of the car body as disclosed. The revolvable platform will include a bearing portion, arranged concentric to the upper rail, adapted to receive the king pin, said bearing portion also being concentric to the operative rail 56 of the bull gear 52, arranged directly below the upper rail. The container ring with rollers or wheels will lie between said operative rail and upper rail.

Means for revolving the platform in either direction may include a pinion meshing with the gear surface or toothed portion 54, a vertical shaft H fixedly carrying the pinion, and means (not shown), desirably on the platform, for supporting and rotating said shaft.
